• Supports standard and Alternistor configurations for versatile AC switching and phase control
• Integrated construction eliminates the need for external discrete trigger components

Triacs Applications

• AC power switching circuits
• Phase control applications
• Temperature modulation controls

Triacs Procurement Notes

Verify the specific suffix 'TP' against official Littelfuse documentation to confirm tape-and-reel packaging or variant specifications. Ensure the order matches the exact 8A rating and voltage class required for the target design. Cross-reference the datasheet revision date to confirm current manufacturing status and compliance with RoHS standards before finalizing procurement.

Triacs Selection Notes

Select this component when designing circuits that require an 8A RMS on-state current with high thermal tolerance. The Alternistor capability offers improved noise immunity compared to standard triacs, making it suitable for environments with significant electrical interference. Confirm that the package type and pinout align with the PCB layout constraints and that the voltage ratings exceed the peak line voltages present in the application.
